SUGGESTED SOLUTIONS
Light or faded print
If a vertical white streak or faded area appears on
the page:
•
The toner supply is low. You may be able to
temporarily extend the toner cartridge life. See
page 61. If this does not improve the print
quality, install a new toner cartridge.
•
The paper may not meet paper specifications;
for example, the paper is too moist or too
rough. See page 31.
•
If the entire page is light, the print resolution
setting is too low. Adjust the print resolution.
See the help screen of the printer driver.
•
A combination of faded or smeared defects
may indicate that the toner cartridge needs
cleaning.
•
The surface of the LSU part inside the machine
may be dirty. Clean the LSU, contact a service
representative.
Toner specks
•
The paper may not meet specifications; for

Dropouts
If faded areas, generally rounded, occur randomly
on the page:
•
A single sheet of paper may be defective. Try
reprinting the job.
•
The moisture content of the paper is uneven or
the paper has moist spots on its surface. Try a
different brand of paper. See page 31.
•
The paper lot is bad. The manufacturing
processes can cause some areas to reject
toner. Try a different kind or brand of paper.
•
Change the printer option and try again. Go to
printer properties, click Paper tab, and set type
to Thick Paper. Refer to the Software section
for details.
If these steps do not correct the problem, contact a
service representative.
White Spots
White spots appear on the page:
•
The paper is too rough and a lot of dirt from the
paper falls to the inner devices within the
machine, which means the transfer belt may be
dirty. Clean the inside of your machine. Contact
a service representative.
•
The paper path may need cleaning. Contact a
service representative.
Vertical lines
If black vertical streaks appear on the page:
•
The drum inside the toner cartridge has
probably been scratched. Remove the toner
cartridge and install a new one. See page 61.
If white vertical streaks appear on the page:
•
The surface of the LSU part inside the machine
may be dirty. Clean the LSU, contact a service
representative.
Color or Black
background
background
If the amount of background shading becomes
unacceptable:
•
Change to a lighter weight paper. See page 31.
•
Check the machine’s environment: very dry
(low humidity) or high humidity (higher than
80% RH) conditions can increase the amount
of background shading.
•
Remove the old toner cartridge and install a
new one. See page 61.
Toner smear
•
Clean the inside of the machine. See page 58.
•
Check the paper type and quality. See page 31.
•
Remove the toner cartridge and install a new
one. See page 61.
